CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of PCT Application Ser. No.PCT/CN2018/085137, filed on Apr. 28, 2018, entitled “Method of PowerControl for Uplink Transmission”, which claims benefit to U.S.Provisional Application No. 62/502,396, filed on May 5, 2017, entitled“Method of Power Control for Uplink Transmission”, the disclosures ofwhich are hereby incorporated herein by reference in their entireties.

TECHNICAL FIELD

The present disclosure relates generally to wireless communication and,in particular embodiments, to a system and method for power control foruplink transmissions.

BACKGROUND

In Long Term Evolution (LTE) networks, each cell is typically served byone transmit/receive point (TRP) that is associated with a unique cellidentifier (ID). In the emerging New Radio (NR) systems, each NR cellmay include multiple TRPs using the same cell ID. An NR cell may cover amuch broader area than an LTE cell. NR systems can support grant-freetransmissions, multi-beam communications, multi-numerologytransmissions, multi-waveform transmissions, multiple reference signalsand other features. Grant-free Physical Uplink Shared Channel (PUSCH)transmissions can include a PUSCH without grant scheduling but with aRadio Resource Control (RRC) connection (e.g., the RRC Connected state)or can include a PUSCH without either grant scheduling or an RRCconnection (e.g., Idle state or RRC_INACTIVE state).

In LTE, the transmission power for the PUSCH can be derived by a userequipment (UE) based on several parameters including the bandwidth ofthe PUSCH resource assignment, the downlink pathloss estimate calculatedin the UE based on a cell-specific reference signal (CRS), acompensation factor for pathloss, dynamic assignment parameters relatedto the modulation and coding scheme (MCS), and a Transmit Power Command(TPC) within the dynamic assignment to adjust a power offset. Anotherfactor used in determining the transmission power for the PUSCH is thePUSCH initial target power, which can have different values depending onthe PUSCH type. In a first type, the PUSCH is scheduled with a dynamicdownlink assignment or grant, a cell-specific component (e.g., initialtarget power1) is provided from a broadcast channel (e.g., the SystemInformation Block (SIB)), and a UE-specific component (e.g., initialtarget power2) is provided by a dedicated channel (e.g., RRC). In asecond type, the PUSCH is semi-persistently scheduled without a dynamicdownlink assignment or grant, and two UE-specific parameters (e.g.,initial target power1 and initial target power2) are used if provided bya dedicated channel (e.g., RRC). Otherwise, a cell-specific component(e.g., initial target power1) is provided from a broadcast channel(e.g., the SIB), and a UE-specific component (e.g., initial targetpower2) is provided by a dedicated channel (e.g., RRC). A third PUSCHtype corresponds to a random access response grant. Parameters that makeup the grant might be provided from a broadcast channel (e.g., the SIB).Different power control may be used for the Sounding Reference Signal(SRS) in different cells, and the power control for the SRS may or maynot be related to that used for the PUSCH.

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

The making and using of embodiments of this disclosure are discussed indetail below. It should be appreciated, however, that the conceptsdisclosed herein can be embodied in a wide variety of specific contexts,and that the specific embodiments discussed herein are merelyillustrative and do not serve to limit the scope of the claims. Further,it should be understood that various changes, substitutions andalterations can be made herein without departing from the spirit andscope of this disclosure as defined by the appended claims.

FIG. 1 is a diagram of a network 100 for communicating data. The network100 comprises a base station no having a coverage area 101, a pluralityof mobile devices 120, and a backhaul network 130. As shown, the basestation no establishes uplink connections 140 and downlink connections150 with the mobile devices 120, which serve to carry data from themobile devices 120 to the base station no and vice versa. Data carriedover the uplink and downlink connections 140 and 150 might include datacommunicated between the mobile devices 120, as well as datacommunicated to and from a remote end (not shown) by way of the backhaulnetwork 130. As used herein, the term “base station” might refer to anycomponent or collection of components configured to provide wirelessaccess to a network, such as an evolved NodeB (eNB), a macro-cell, afemtocell, a Wi-Fi access point (AP), or other wirelessly enableddevices. Base stations might provide wireless access in accordance withone or more wireless communication protocols, such as NR, LTE, LTEAdvanced (LTE-A), High Speed Packet Access (HSPA), or Wi-Fi802.11a/b/g/n/ac. As used herein, the term “user equipment” (UE) mightrefer to any component or collection of components capable ofestablishing a wireless connection with a base station, such as a mobilestation (STA), or other wirelessly enabled devices. In some embodiments,the network 100 might comprise various other wireless devices, such asrelays or low power nodes.

It is contemplated that future NR wireless networks might supportseparate power control processes for transmission of different datachannels or reference signals, such as the PUSCH, the SRS, and thePhysical Uplink Control Channel (PUCCH). In NR systems that usebeamforming, the NR standards might support beam-specific power control.The NR standards might support numerology-specific and/orwaveform-specific power control. Numerology refers to the set ofphysical layer parameters and might in some cases refer specifically tothe subcarrier spacing and the Cyclic Prefix (CP) length, and a waveformcan be orthogonal frequency division multiplexing (OFDM) or DiscreteFourier Transform Spread OFDM (DFT-S-OFDM). It is further contemplatedthat future NR wireless networks might support traffic-specific cases,which might be associated with other physical properties or parameters(e.g., numerology, radio network temporary identifier (RNTI), etc.). Forthese and other reasons, improved uplink power control schemes might beneeded for use in NR systems.

The present disclosure provides embodiments related to power control forthe PUSCH and the SRS in NR systems. In particular embodiments, aplurality of power control sets having different values of power controlparameters is made available to a UE. The UE is provided withinformation associating each of the power control sets with one or moreproperties related to the operation of the UE. The providing schememight be at least one of predefinition, broadcast signaling anddedicated signaling from the network side. When one or more of theoperational properties is in effect on the UE, the UE uses the powercontrol set associated with the one or more of the operationalproperties to transmit a PUSCH and/or an SRS. A traffic-specific powercontrol set might be associated with one or more specific physical layeridentifiers, such as an RNTI. In addition, a power control set might beassociated with one or more resource unit-specific parameters, such asnumerology or a scheduling time unit length for PUSCH. Furthermore,power control sets that are SRS-specific might or might not useprecoding and/or beamforming, might support different precoding and/orbeamforming selection, and might support multiple numerologies. Inaddition, for a PUSCH and/or an SRS, a specific power control set mightbe associated with a waveform type and/or a pathloss-associatedreference signal type.

Power control for the PUSCH will now be considered. In an embodiment, aUE is provided with at least two separate power control parameter setsfor different PUSCH transmissions. The power control parameters in a setmight include at least one of a cell-specific PUSCH initial targetpower, a UE group-specific PUSCH initial target power, a UE-specificPUSCH initial target power, a pathloss, a pathloss compensation factor,and/or a separate Transmit Power Command (TPC). The UE selects one ofthe power control sets for a PUSCH transmission based on the selectedpower control set's preconfigured association with one or moreproperties associated with the UE. For PUSCH transmissions, theproperties associated with the UE might include at least one of resourceassignment-associated properties, a control resource set for a PhysicalDownlink Control Channel (PDCCH), a scheduling unit length for PUSCH,downlink control information (DCI)-related information, a waveform typefor PUSCH, and/or a downlink (DL) reference signal (RS) type forpathloss estimation.

FIG. 2 summarizes some PUSCH-related cases. In this and subsequentsimilar drawings, frequency is represented on the vertical axis and timeis represented on the horizontal axis. The dashed lines 210 and 220distinguish different numerologies. It can be seen that, above thehorizontal dashed line 210, a smaller subcarrier spacing and longer timeunits are used, and below the horizontal dashed line 210, a largersubcarrier spacing and smaller time units are used. To the left of thevertical dashed line 220, different NR-PDCCHs are present. Each NR-PDCCHmight be configured with one resource set, and each resource set mightbe configured with one specific numerology. That is, a numerology mightbe associated with a NR-PDCCH channel and a resource set. To the rightof the vertical dashed line 220, traffic might be distinguished as PUSCHUltra-Reliable and Low-Latency Communications (URLLC) and PUSCH EnhancedMobile Broadband (eMBB). The different types of traffic might beassociated with different numerologies and different time unit lengths.Alternatively, different numerologies might be used for the same type oftraffic.

In an embodiment, as mentioned above, a UE might select a power controlset for a PUSCH transmission based on the selected power control set'spreconfigured association with a resource assignment type. Thepreconfiguration scheme might be at least one of predefinition,broadcast signaling and dedicated signaling from the network side. Theresource assignment type might be a resource assignment based only onDCI, might be a resource assignment based on DCI together with RRCand/or system information, or might be a resource assignment based onlyon RRC and/or system information. In the latter case, there is no DCIdetection by the UE. One of the resource assignment types might beassociated with a first power control set, and another of the resourceassignment types might be associated with a second power control set. Asa first example, a UE might use the first power control set whendetermining the PUSCH resource assignment based only on DCI and use thesecond power control set when determining the PUSCH resource assignmentbased only on RRC and/or system information. As a second example, apathloss compensation factor of the first power control set might beconfigured by RRC signaling, and a pathloss compensation factor of thesecond power control set might be fixed. As a third example, a pathlossof the first power control set might be estimated based on theUE-specific DL RS for L3 measurement and/or L1/L2 measurement, and apathloss of the second power control set might be estimated based onlyon the synchronization signal for L3 measurement.

FIG. 3 illustrates an embodiment where a power control set for a PUSCHtransmission is selected based on an association with a resourceassignment type. In a first association 310, RRC and/or SIB togetherwith a first DCI 312 are associated with a first PUSCH 314. In a secondassociation 320, a second DCI 322 is associated with a second PUSCH 324.In a third association 330, RRC and/or SIB alone 332 are associated witha third PUSCH 334, and DCI is not used. The PUSCHs 314, 324, and 334 aretransmitted with the power control sets associated with the resourceassignment types.

In an embodiment, as mentioned above, a UE might select a power controlset for a PUSCH transmission based on the selected power control set'spreconfigured association with a control resource set for PUSCHassignment. The preconfiguration scheme might be at least one ofpredefinition, broadcast signaling and dedicated signaling from thenetwork side. The control resource set might be associated with acontrol resource set index and/or a control resource set-associatednumerology. One of the control resource sets might be associated with afirst power control set, and another of the control resource sets mightbe associated with a second power control set. As a first example, if aUE detects a DCI for PUSCH from a control resource set associated with afirst index and/or a first numerology, the first power control set mightbe used for PUSCH power control. The second power control set might beused once the UE detects a DCI for PUSCH from a control resource setassociated with another index and/or another numerology. As a secondexample, a first cell-specific PUSCH initial target power for the firstpower control set and a second cell-specific PUSCH initial target powerfor the second power control set might be configured by the systeminformation. As a third example, a first UE-specific PUSCH initialtarget power for the first power control set and a second UE-specificPUSCH initial target power for the second power control set might beconfigured by RRC signaling. As a fourth example, a first pathlosscompensation factor for the first power control set might be fixed ormight be configured by RRC signaling, and a second pathloss compensationfactor for the second power control set might be configured by RRCsignaling. As a fifth example, a first TPC might be used for the firstpower control set, and a second TPC might be used for the second powercontrol set.

FIG. 4 illustrates an embodiment where a power control set for a PUSCHtransmission is selected based on an association with a control resourceset. A first control resource set 410 with a first numerology is usedfor a first PUSCH transmission 430, and a second control resource set420 with a second numerology is used for a second PUSCH transmission440. Different traffic might be associated with the differentnumerologies. An uplink grant might be associated with a controlresource set and a specific numerology. The PUSCHs 430 and 440 aretransmitted with the power control sets associated with the controlresource sets 410 and 420.

In an embodiment, as mentioned above, a UE might select a power controlset for a PUSCH transmission based on the selected power control set'spreconfigured association with a scheduling time unit length for PUSCH.The preconfiguration scheme might be at least one of predefinition,broadcast signaling and dedicated signaling from the network side. Thescheduling time unit length for the PUSCH transmission might be a numberof OFDM symbols, a mini-slot, a slot, and/or a slot group. One of thescheduling time units might be associated with a first power controlset, and another of the scheduling time units might be associated with asecond power control set. As a first example, if a UE detects ascheduling time unit length with two OFDM symbols from a DCI for PUSCH,the first power control set might be used for PUSCH power control. Thesecond power control set might be used once the UE detects anotherscheduling time unit length with seven OFDM symbols from a DCI. As asecond example, a first cell-specific PUSCH initial target power for thefirst power control set and a second cell-specific PUSCH initial targetpower for the second power control set might be configured by the systeminformation. As a third example, a common cell-specific PUSCH initialtarget power for both the first power control set and the second powercontrol set might be configured by the system information. As a fourthexample, a first UE-specific PUSCH initial target power for the firstpower control set and a second UE-specific PUSCH initial target powerfor the second power control set might be configured by RRC signaling.As a fifth example, a first pathloss compensation factor for the firstpower control set might be fixed or might be configured by RRCsignaling, and a second pathloss compensation factor for the secondpower control set might be configured by RRC signaling. As a sixthexample, a first TPC might be used for the first power control set, anda second TPC might be used for the second power control set.

FIG. 5 illustrates an embodiment where a power control set for a PUSCHtransmission is selected based on an association with a scheduling timeunit length. A first scheduling unit length 510 is associated with afirst PUSCH 530, and a second scheduling unit length 520 is associatedwith a second PUSCH 540. The PUSCHs 530 and 540 are transmitted with thepower control sets associated with the scheduling time unit lengths 510and 520.

In an embodiment, as mentioned above, a UE might select a power controlset for a PUSCH transmission based on the selected power control set'spreconfigured association with DCI-related information. Thepreconfiguration scheme might be at least one of predefinition,broadcast signaling and dedicated signaling from the network side. TheDCI-related information for the PUSCH transmission might be anassociated RNTI for a DCI mask and/or might be a DCI format orstructure. Some DCI-related information might be associated with a firstpower control set, and other DCI-related information might be associatedwith a second power control set. As a first example, if a UE that ispreconfigured with more than one RNTI detects a DCI for PUSCH which ismasked with a first RNTI, the first power control set might be used forPUSCH power control. The second power control set might be used once theUE detects a DCI with a second RNTI. As a second example, if a UE thatis preconfigured with more than one DCI format detects a DCI for PUSCHwith a first format, the first power control set might be used for PUSCHpower control. The second power control set might be used once the UEdetects a DCI with a second format. As a third example, a firstcell-specific PUSCH initial target power for the first power control setand a second cell-specific PUSCH initial target power for the secondpower control set might be configured by the system information. As afourth example, a common cell-specific PUSCH initial target power forboth the first power control set and the second power control set mightbe configured by the system information. As a fifth example, a firstUE-specific PUSCH initial target power for the first power control setand a second UE-specific PUSCH initial target power for the second powercontrol set might be configured by RRC signaling. As a sixth example, afirst pathloss compensation factor for the first power control set mightbe fixed or might be configured by RRC signaling, and a second pathlosscompensation factor for the second power control set might be configuredby RRC signaling. As a seventh example, a first TPC might be used forthe first power control set, and a second TPC might be used for thesecond power control set.

FIG. 6A illustrates an embodiment where a power control set for a PUSCHtransmission is selected based on an association with DCI-relatedinformation. The DCI-related information is a plurality of RNTIs in thiscase. A first RNTI 610 is associated with a first PUSCH 630, and asecond RNTI 620 is associated with a second PUSCH 640. The PUSCHs 630and 640 are transmitted with the power control sets associated with theRNTIs 610 and 620.

FIG. 6B illustrates another embodiment where a power control set for aPUSCH transmission is selected based on an association with DCI-relatedinformation. The DCI-related information is a DCI format in this case. Afirst DCI format 650 is associated with a first PUSCH 670, and a secondDCI format 660 is associated with a second PUSCH 680. The PUSCHs 670 and680 are transmitted with the power control sets associated with the DCIformats 650 and 660.

In an embodiment, as mentioned above, a UE might select a power controlset for a PUSCH transmission based on the selected power control set'spreconfigured association with a waveform type for PUSCH. Thepreconfiguration scheme might be at least one of predefinition,broadcast signaling and dedicated signaling from the network side. Thewaveform type for the PUSCH transmission might be OFDM or might beDFT-S-OFDM. One waveform might be associated with a first power controlset, and another waveform might be associated with a second powercontrol set. As a first example, if a UE is configured with OFDM forPUSCH, the first power control set might be used for PUSCH powercontrol. The second power control set might be used once the UE isconfigured with DFT-S-OFDM. As a second example, a first cell-specificPUSCH initial target power for the first power control set and a secondcell-specific PUSCH initial target power for the second power controlset might be configured by the system information. As a third example, acommon cell-specific PUSCH initial target power for both the first powercontrol set and the second power control set might be configured by thesystem information. As a fourth example, a first UE-specific PUSCHinitial target power for the first power control set and a secondUE-specific PUSCH initial target power for the second power control setmight be configured by RRC signaling. As a fifth example, a firstpathloss compensation factor for the first power control set might beconfigured by RRC signaling, and a second pathloss compensation factorfor the second power control set might be fixed or might be configuredby RRC signaling. As a sixth example, a first TPC might be used for thefirst power control set, and a second TPC might be used for the secondpower control set.

FIG. 7 illustrates an embodiment where a power control set for a PUSCHtransmission is selected based on an association with a waveform type.At 710, an OFDM waveform is associated with a first PUSCH, and at 720 aDFT-S-OFDM waveform is associated with a second PUSCH.

In an embodiment, as mentioned above, a UE might select a power controlset for a PUSCH transmission based on the selected power control set'spreconfigured association with a DL RS type for pathloss estimation. Thepreconfiguration scheme might be at least one of predefinition,broadcast signaling and dedicated signaling from the network side. TheDL RS type for pathloss estimation might be both a synchronizationsignal for Layer3 measurement and a UE-specific RS for Layer3measurement; or might be both a UE-specific RS for Layer3 measurementand a UE-specific RS for Layer1 and/or Layer2 measurement; or mightinclude a synchronization signal for Layer3 measurement, a UE-specificRS for Layer3 measurement, and a UE-specific RS for Layer1 and/or Layer2measurement. A DL RS type for pathloss estimation might be associatedwith a first power control set, and another DL RS type for pathlossestimation might be associated with a second power control set. Forexample, once a UE is configured to estimate pathloss based on both L3Reference Signal Received Power (RSRP) of a synchronization signal andL3 RSRP of a UE-specific Channel State Information Reference Signal(CSI-RS), the first power control set might be used for PUSCH powercontrol. The second power control set might be used once the UE isconfigured to estimate pathloss based on both L3 RSRP of a UE-specificCSI-RS and L1 RSRP of a UE-specific CSI-RS or based on L3 RSRP of aUE-specific CSI-RS, L3 RSRP of a UE-specific CSI-RS, and L1 RSRP of aUE-specific CSI-RS.

FIG. 8 illustrates an embodiment where a power control set for a PUSCHtransmission is selected based on an association with a DL RS type forpathloss estimation. A pathloss associated with a first reference signaltype 810 is associated with a first PUSCH 820, and a pathloss associatedwith a second reference signal type 830 is associated with a secondPUSCH 840.

In an embodiment, a UE computes a plurality of power headrooms for aplurality of PUSCH transmissions associated with different schedulingtime unit lengths. The scheduling time unit lengths might be a number ofOFDM symbols, a mini-slot, a slot, a slot group and/or an OFDM symboltime length associated with a specific numerology. A UE might generatedifferent power headroom reports associated with different time unitlengths or different numerologies. If the UE transmits a first PUSCHassociated with a first scheduling time unit length, a first powerheadroom might be computed based on the power control set parameters forthe first PUSCH. If the UE transmits a second PUSCH associated with asecond scheduling time unit length, a second power headroom might becomputed based on the power control set parameters for the second PUSCH.

FIG. 9 illustrates embodiments of different power headroom reportingunits. For a first numerology 910, the time unit for a first powerheadroom report is a slot 930, the time unit for a third power headroomreport is a mini-slot 940, and the time unit for a fourth power headroomreport is a symbol set 950. For a second numerology 920, the time unitfor a second power headroom report is a slot 960. The slot 910 for thesecond numerology 920 might have a different size from the slot 930 forthe first numerology 910.

In general, for the PUSCH, a first set with power control-relatedparameters {P0_1 (the sum of the cell-specific power and the UE-specificpower), Alpha_1 (the pathloss compensation factor), PL_1 (the pathloss),f_1 (the transmit power command)} is used for PUSCH1 with one or acombination of {BWP1 (the bandwidth part) or numerology1, resourceassignments, DCI_Info1, SRI1 (the SRS resource index), and DL RS type1},and a second set with power control-related parameters {P0_2, Alpha_2,PL_2, f_2} is used for PUSCH2 with one or a combination of {BWP2 ornumerolgoy2, resource assignment2, DCI_Info2, SRI2, and DL RS type2}.Alpha_1 and Alpha_2 might be the same.

Power control for the SRS will now be considered. In an embodiment, a UEis provided with at least two separate power control parameter sets fordifferent SRS transmissions. The power control parameters in a set mightinclude at least one of a cell-specific PUSCH initial target power, a UEgroup-specific PUSCH initial target power, a UE-specific PUSCH initialtarget power, a UE-specific SRS initial target power, a pathloss, apathloss compensation factor, and/or a separate TPC. The UE selects oneof the power control sets for an SRS transmission based on the selectedpower control set's preconfigured association with one or moreproperties associated with the UE. For SRS transmissions, the propertiesassociated with the UE might include resource information, such as thebeamforming and/or precoding related information used in a beamformingand/or precoding scenario, numerology information, a scheduling timeunit length for the associated PUSCH, a waveform type for SRS, and/or aDL RS type for pathloss estimation.

In an embodiment, a UE selects a power control set for an SRStransmission based on the selected power control set's preconfiguredassociation with resource information for SRS transmission. Thepreconfiguration scheme might be at least one of predefinition,broadcast signaling and dedicated signaling from the network side. Theresource information might be a configured resource index for SRStransmission (i.e., SRS resource index, (SRI)), or might beQuasi-Co-Location (QCL) information with a downlink CSI-RS, and/or mightbe a panel or beam pair link (BPL) index. The UE might transmit the SRSwith or without beamforming and with or without precoding. Whenbeamforming and/or precoding is used, beam-specific and/or precodingpower control might be used, and the resource information might indicateto the UE whether beamforming and/or precoding will be used for SRStransmission. Moreover, the resource information might also include thetransmission beam selection, which might be based on a networkindication or might be triggered by the UE. A first portion of theresource information might be associated with a first power control set,and a second portion of the resource information might be associatedwith a second power control set. As a first example, a UE that isconfigured with multiple resource indexes for SRS transmission for beampair link measurement and configured with resource-specific powercontrol might use the first power control set for SRS transmitted with afirst resource index and use the second power control set for SRStransmitted with a second resource index. As a second example, a UE thatis configured with multiple resource indexes for SRS transmission forbeam pair link measurement and configured with resource common powercontrol might use a third power control set for SRS transmitted withdifferent resource indexes. As a third example, a UE might use the thirdpower control set for SRS when not configured with precoding and/orbeamforming, and might use the first or second power control set for SRSwhen configured with precoding and/or beamforming. As a fourth example,a UE might use the third power control set for SRS when not configuredwith precoding and/or beamforming selection information and might usethe first or second power control set for SRS when configured withprecoding and/or beamforming selection information. The configurationscheme might be at least one of predefinition, broadcast signaling anddedicated signaling from the network side.

The first power control set for the SRS might be partially derived fromthe power control set for the first PUSCH associated with the firstportion of the resource information, and the second power control setfor the SRS might be partially derived from the power control set forthe second PUSCH associated with the second portion of the resourceinformation. For example, the first power control set for the SRS mightbe derived from at least one of the first cell-specific PUSCH initialtarget power; first UE group-specific PUSCH initial target power; firstUE-specific PUSCH initial target power; first pathloss; first pathlosscompensation factor; and first transmit power command which is for thefirst PUSCH. The second power control set for the SRS might be derivedfrom at least one of the second cell-specific PUSCH initial targetpower; second UE group-specific PUSCH initial target power; secondUE-specific PUSCH initial target power; second pathloss; second pathlosscompensation factor; and second transmit power command which is for thesecond PUSCH. The third power control set for the SRS might be partiallyderived from the power control set for the PUSCH associated withreference resource information that may or may not be the same as thefirst and/or second portion of the resource information and/or from aseparate power control set that is not associated with any PUSCH. As afirst example, a UE-specific SRS initial target power for the thirdpower control set for SRS might be derived from at least one of a firstcell-specific PUSCH initial target power and a first UE-specific PUSCHinitial target power for an associated first PUSCH, or from at least oneof a second cell-specific PUSCH initial target power and a secondUE-specific PUSCH initial target power for an associated second PUSCH.As a second example, a UE-specific SRS-specific initial target power forthe third power control set for SRS might be independently configured byRRC signaling. As a third example, a pathloss for the third powercontrol set for SRS might be derived from one of a first pathloss for anassociated first PUSCH and a second pathloss for an associated secondPUSCH. As a fourth example, a pathloss for the third power control setfor SRS might be derived from both a first pathloss for an associatedfirst PUSCH and a second pathloss for an associated second PUSCH. As afifth example, a pathloss compensation factor for the third powercontrol set for SRS might be the same as one of a first pathlosscompensation factor for an associated first PUSCH and a second pathlosscompensation factor for an associated second PUSCH. As a sixth example,a pathloss compensation factor for the third power control set for SRSmight be fixed or might be independently configured by RRC signaling. Asa seventh example, a transmit power command for the third power controlset for SRS might be derived from one of a first transmit power commandfor an associated first PUSCH and a second transmit power command for anassociated second PUSCH. As an eighth example, a transmit power commandfor the third power control set for SRS might be derived from both afirst transmit power command for an associated first PUSCH and a secondtransmit power command for an associated second PUSCH.

FIG. 10A illustrates an embodiment in a beamforming scenario where,among beams transmitted by a UE, a first beam 1010 carrying an SRS isassociated with a first beam 1030 carrying a PUSCH, and a second beam1020 carrying an SRS is associated with a second beam 1040 carrying aPUSCH. FIG. 10B illustrates an embodiment in a beamforming scenariowhere, among beams transmitted by a UE, the first beam 1010 carrying anSRS and the second beam 1020 carrying an SRS are both associated withthe first beam 1030 carrying a PUSCH.

In an embodiment, in a case where a UE selects a power control set foran SRS transmission based on the selected power control set'spreconfigured association with numerology information for SRStransmission, the numerology information might be a configurednumerology for SRS transmission and/or a configured numerology for acontrol resource set from which DCI for triggering the SRS transmissionmight be monitored. In the case where the numerology information is aconfigured numerology for SRS transmission, the configuration schememight be based on a dynamic indication and/or an RRC configuration. Afirst portion of the numerology information might be associated with afirst power control set, and a second portion of the numerologyinformation might be associated with a second power control set. Thefirst power control set for the SRS might be partially derived from thepower control set for the PUSCH associated with the first portion of thenumerology information. The second power control set for the SRS mightbe partially derived from the power control set for the PUSCH associatedwith the second portion of the numerology information. As a firstexample, a UE that is configured with multiple resource sets withdifferent numerologies for SRS transmission might use the first powercontrol set for SRS transmitted with a first numerology and use thesecond power control set for SRS transmitted with a second numerology.As a second example, a UE that is configured with multiple controlresource sets with different numerologies for SRS transmission might usethe first power control set for SRS transmission that is triggered bythe DCI detected from the first control resource set and use the secondpower control set for SRS transmission that is triggered by the DCIdetected from a second control resource set.

FIG. 11 illustrates an embodiment where a power control set for an SRStransmission is selected based on an association with numerologyinformation. A first resource set 1110 with a first numerology includesindication signaling that triggers a first SRS transmission 1130, and asecond resource set 1120 with a second numerology includes indicationsignaling that triggers a second SRS transmission 1140. If a UE detectsSRS transmission trigger signaling in a first PUSCH 1150, the UE uses afirst power control set. If the UE detects SRS transmission triggersignaling in a second PUSCH 1160, the UE uses a second power controlset.

In an embodiment, a UE selects a power control set for an SRStransmission based on the selected power control set's preconfiguredassociation with a scheduling time unit length for an associated PUSCH.The preconfiguration scheme might be at least one of predefinition,broadcast signaling and dedicated signaling from the network side. Thescheduling time unit length for the associated PUSCH transmission mightbe a number of OFDM symbols, a mini-slot, a slot, and/or a slot group. Afirst SRS associated with a PUSCH with a first scheduling time unitlength might be associated with a first power control set, and a secondSRS associated with a PUSCH with a second scheduling time unit lengthmight be associated with a second power control set. The first powercontrol set for the first SRS might be partially derived from the powercontrol set for the PUSCH associated with the first scheduling time unitlength. The second power control set for the second SRS might bepartially derived from the power control set for the PUSCH associatedwith the second scheduling time unit length. An association with thePUSCH scheduling time unit length might be provided based on an RRCconfiguration and/or DCI that supports PUSCH assignment and an SRStrigger. For example, a UE that is configured with multiple PUSCHscheduling time unit lengths might use the first power control set forSRS transmission that is triggered by a DCI detected with a firstscheduling time unit length and might use the second power control setfor SRS transmission that is triggered by a DCI detected with a secondscheduling time unit length.

FIG. 12 illustrates an embodiment where a power control set for an SRStransmission is selected based on an association with a scheduling timeunit length. A first scheduling unit length 1210 is associated with afirst PUSCH 1230, and a second scheduling unit length 1220 is associatedwith a second PUSCH 1240. The first PUSCH 1230 is associated with afirst SRS 1250, and the second PUSCH 1240 is associated with a secondSRS 1260.

In an embodiment, a UE selects a power control set for an SRStransmission based on the selected power control set's preconfiguredassociation with a waveform type for SRS. The preconfiguration schememight be at least one of predefinition, broadcast signaling anddedicated signaling from the network side. The waveform type for the SRStransmission might be OFDM or might be DFT-S-OFDM. A first SRSassociated with a first waveform type might be associated with a firstpower control set, and a second SRS associated with a second waveformtype might be associated with a second power control set. As a firstexample, a UE that is configured with waveform types might use the firstpower control set for SRS transmission with OFDM and might use thesecond power control set for SRS transmission with DFT-S-OFDM. As asecond example, a UE that is configured with multiple pathlosscompensation factors might use the first pathloss compensation factorfor SRS transmitted with a first waveform type and use the secondpathloss compensation factor for SRS transmitted with a second waveformtype.

FIG. 13 illustrates an embodiment where a power control set for an SRStransmission is selected based on an association with a waveform typefor SRS. At 1310, an OFDM waveform is associated with a first SRS, andat 1320 a DFT-S-OFDM waveform is associated with a second SRS.

In an embodiment, a UE selects a power control set for an SRStransmission based on the selected power control set's preconfiguredassociation with a DL RS type for pathloss estimation.

TheDL RS type for pathloss estimation might be both a synchronizationsignal for Layer3 measurement and a UE-specific RS for Layer3measurement; or might be both a UE-specific RS for Layer3 measurementand a UE-specific RS for Layer1 and/or Layer2 measurement; or mightinclude a synchronization signal for Layer3 measurement, a UE-specificRS for Layer3 measurement, and a UE-specific RS for Layer1 and/or Layer2measurement. A DL RS type for pathloss estimation might be associatedwith a first power control set, and another DL RS type for pathlossestimation might be associated with a second power control set. Forexample, once a UE is configured to estimate pathloss based on both L3RSRP of a synchronization signal and L3 RSRP of a UE-specific CSI-RS,the first power control set might be used for PUSCH power control. Thesecond power control set might be used once the UE is configured toestimate pathloss based on both L3 RSRP of a UE-specific CSI-RS and LiRSRP of a UE-specific CSI-RS or based on L3 RSRP of a UE-specificCSI-RS, L3 RSRP of a UE-specific CSI-RS, and L1 RSRP of a UE-specificCSI-RS.
